Whether you think form follows function or function follows form, the Pentimento House proves that form and function can work gracefully together. An elegant and contemporary version of the Lincoln Log House, architects Jose Maria Sáez and David Barragán purposefully stacked prefabricated concrete pieces so that spaces were left in-between, allowing air to flow through the home while still maintaining a feeling of separation between indoors and outdoors. If that isn’t enough, the spaces are functional in another way — wood slats can be inserted in the narrow openings to create tables, benches, or stair treads that integrate flawlessly into the design of the home.
